Self Adhered Flashing Helps Seal the Building Envelope

DuPont™ FlexWrap™ NF self adhered flashing does not require mechanical fasteners, even in flexed corner areas around building openings. This allows it to provide easy, one-step insulation for hard-to-seal corners around windows and doors.

FlexWrap™ NF is designed to help protect vulnerable corners against air and water intrusion, as part of a complete DuPont Building Envelope Solution. It’s effective across a range of window and door designs and a wide range of typical wall substrates, including OSB, plywood, gypsum, concrete masonry unit (CMU) and other non-nailable sheathing materials.

How it Works

FlexWrap™ NF integrates easily with all DuPont air and water barriers, to help seal the building envelope for improved durability and energy efficiency.

Correctly installed, FlexWrap™ NF can help stop water from getting at the corners of windows and doors. In turn, that can help prevent water damage, such as wood rot and corrosion, as well as mold. Keeping air and water out can also help maintain insulation R-value, for improved energy efficiency.

One Step Installation

The “NF” in DuPont™ FlexWrap™ NF means “no fasteners.” Instead, DuPont™ FlexWrap™ NF is a self adhered, extendable flashing backed with a 100% butyl-based adhesive layer, making one-step installation – and protection – possible. And because it’s an extendible flashing material, DuPont™ FlexWrap™ NF can be stretched and wrapped into a rough window opening before the window is installed, or flashed around arched or custom-shaped windows, as well as other wall penetrations.

So FlexWrap™ NF isn’t just an effective flashing to seal out water, it’s also a cost- and time-effective material for crews to work with on the job site.

When a self adhered flashing material is the right choice– due to variations in the substrate material, unique spatial challenges, custom window shapes, or other consideration —DuPont™ FlexWrap™ NF delivers a practical, integrated solution.
